Daemon.err hostapd: nl80211: kernel reports: key addition failed - is this a problem?

Same error with DIR-882 A1 and 22.03.0-rc5 r19523.

Has anyone tried with Generate PMK locally OFF?

Yes. Same error message. But in general it seems to work most times.

From my understanding the bug wasn't present on my Xiaomi Mi Router 4a Gigabit Edition in build r19306.
Now with 22.03.0-rc5 I can definitely see it too.

How do you know that it works ? :slight_smile:
change from AP to AP is done, but is it 802.11r way ?

Very good Point. How to find out for sure?

You can activate logging for Wi-Fi and check if 4-way handshake is shortened. In my case it worked in 50% but if this error is thrown it does not handle it with FT.
